Credit card interest rates are high for high amounts

If you do not have personal savings with which to fund your invention, you could use your credit cards. This is a slippery slope, however. Never charge more than you can easily pay back within a reasonably short time. Credit card interest rates are among the highest and using credit cards for large amounts that must be paid back over an extended period of time is not a wise course of action. It is appropriate to use your credit card for small purchases of prototype materials or prototyping services, for example, especially if you are like us and like to get air miles for nearly everything you purchase.
